Notley said this week Alberta is preparing to punish B.C. with legislation that could restrict the flow of oil to the West Coast, likely causing a spike in gasoline prices, which currently hover around $1.50 a litre in Metro Vancouver.

Notley also said Alberta is prepared to take over the pipeline.

The federal government approved the project, which would triple capacity of the pipeline running between Edmonton and Burnaby in 2016.

Trudeau has repeatedly said Trans Mountain is in the national interest and will get built.

B.C.’s Energy, Mines and Petroleum Resources Ministry said in a statement Friday that Kinder Morgan must still submit about 600 permits for the expansion.

It said the submitted permits must align with 37 conditions outlined in B.C.’s environmental certificate and the 157 conditions detailed in the National Energy Board’s approval.

Horgan said Friday that B.C. is heading to court to test its jurisdictional authority over the pipeline, but until then, the government is not holding up the expansion.

“We are not thwarting the project,” he said. “We are issuing permits as they ask for them.”

But the provincial government will continue to state its belief that the pipeline poses environmental and economic risks that are too great, Horgan added.

“I do believe we have a mandate to defend the coast,” he said. “I would also argue the premier of B.C. has an obligation at all times to stand up for the jurisdictional authority of provincial rights.”
